How can i recive Selected Index Page in UIScrollView

Question

Hi all, I'm a beginner of iPhone development. I also set 95 pages with (320, 480)pixel in scrollView' content size.
I want to get selected index number when i scroll in UIScrollView. My code is here;

• (void)viewDidLoad { [super viewDidLoad];

  NSLog(@"Selected page %d",scrollView.contentOffset.x) ;

  scrollView.pagingEnabled = YES;

  NSUInteger i;

  for (i = 1; i <= kNumImages; i++) {

  NSString *imageName = [NSString stringWithFormat:@"page (%d).png", i];

  UIImage *image = [UIImage imageNamed:imageName];

  UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

  CGRect rect = imageView.frame;

  rect.size.height = kScrollObjHeight;

  rect.size.width = kScrollObjWidth;

  imageView.frame = rect;

  imageView.tag = i;

  NSLog(@"Selected page %d",scrollView.contentOffset.x) ;

  [scrollView addSubview:imageView];

   [imageView release];
  

  }

  [self layoutScrollImages];

}

Hope Help!
